The sandy wash at the bottom of the canyon is primarily where I searched for cougar tracks. I also searched under small shrubs and trees for cached cougar kills. Cougar often prefer to travel in the narrow washes with it's associated brush and taller vegetation for concealment. The mammal diversity in the canyon was apparent from the abundant tracks I did find: coyoted, gray fox, cottontail, jackrabbit, kangaroo rat, skunk, mule deer, bighorn sheep, and what I believe was javelina.
